Abstract
Apparatus and methods for temporarily sealing a pipe including apparatus and methods for creating a temporary airtight seal at the open end of a pipe in a plumbing or refrigeration system. One such apparatus includes a body, grommet, washer, and a nut. Multiple airtight seals are created including a first primary seal between an exterior of the pipe and the grommet and a secondary seal between the open end of the pipe and the washer. The grommet does not require teeth and the apparatus does not require adhesive, sealant, or any other type of similar materials. Use of the apparatus and methods greatly minimizes and/or eliminates the potential for marring or otherwise distorting the open end of the pipe, thereby facilitating reuse of same.
